This book explains the evolutions of architecture for mobiles and
summarizes the different technologies:
- 2G: the GSM (Global System for Mobile) network, the GPRS (General
Packet Radio Service) network and the EDGE (Enhanced Data for Global
Evolution) evolution;
- 3G: the UMTS (Universal Mobile Telecommunications System) network and
the HSPA (High Speed Packet Access) evolutions:
- HSDPA (High Speed Downlink Packet Access),
- HSUPA (High Speed Uplink Packet Access),
- HSPA+;
- 4G: the EPS (Evolved Packet System) network.
The telephone service and data transmission are the two main services
provided by these networks. The evolutions are fundamentally dictated by
the increase in the rate of data transmission across the radio interface
between the network and mobiles.
This book is intended as a readily understandable support to help
students and professionals wishing to quickly acquire the main concepts
of networks for mobiles understand the technologies deployed.
